Ignoring the fact that Colin Farrell's name sounds just about as Irish as it gets, there's still a shred of possibility that the southern drawl he spits as Jesse James throughout "American Outlaws" actually fooled a few theatergoers into thinking that this bushy-eyebrowed ladykiller was actually born a stars n' stripes yankee.

Let's face it: Farrell -- who currently stars in the new crime thriller "Dead Man Down" -- is a verbal chameleon, a man who has effortlessly toggled the fader on his pipes between his real Dublin-derived brogue and a convincing down-home All-American inflection throughout his two-decade-long career. Practically every role he's taken on has fit somewhere between those two points, but you'd have to subject yourself to a full-on Farrell filmography marathon to know just where each film ranks within his verbal spectrum. Accent charting clearly can't be accomplished overnight, especially when Colin Farrell is involved.

In the interest of creating the definitive document of Farrell's vocal acrobatics, Nick Blake (data) and Nick DeSantis (artwork) have created the graphic below, ranking Colin Farrell's movies from those that feature his most American accents to those showcasing his most Irish accents. Only "The Way Back" (2010) isn't applicable due to his character being Russian.
